Blacks are so bad at replacing batteries in their smoke detectors that a lot of blue states like
New York,
Illinois,
Connecticut, etc. have changed laws to make it illegal for retailers to sell/install smoke detectors that rely on replaceable batteries, instead requiring you to buy smoke detectors with sealed batteries made to last at least 10 years (i.e. the full lifetime of the smoke detector). California has had this in place since 2014, but I was surprised to see that Florida and Texas also passed similar smoke alarm laws. If you live in the US, you can check your state
here.
They're considerably more expensive upfront, like more than it even would've cost to buy 10 years worth of batteries.
By the way, if you're one of those retards that removed your smoke detectors because it goes off every time you cook,
you might just have the wrong type of smoke alarm near your kitchen. Try replacing it with a photoelectric alarm.
For ultimate peace of mind, pick up a small A-B-C fire extinguisher from the hardware store for ~$25 while you're at it.
